When the router's routing table doesn't contain the MAC addresses of devices on the
local LAN that they need to forward frames to. - CORRECT ANSWER-When does a
router use ARP?
Hosts use ARP to resolve known IP addresses into MAC addresses. - CORRECT
ANSWER-Routing data between computers on a network requires several mappings
between different addresses. Which of the following statements is true?
